Abstract: A Laser Induced Breakdown Spectrocopy (LIBS) system for the analysis of a sample pellet of a consolidated granular material retained in a tubular container may include a laser source configured to emit a pulsed laser beam towards an exposed surface of the sample pellet; and a sample station configured to hold the cylindrical tubular container in one or more orientations to present an exposed surface of the sample pellet towards the pulsed laser beam. The sample station may induce linear movement of the sample pellet along an axis and to expose a portion of the outer side surface of the sample pellet previously constrained through contact with an inner surface of the cylindrical tubular container. The sample station may induce rotational motion of the outer side surface of the sample pellet around the movement axis to present the portion of the outer side surface as the exposed surface.

Abstract: A sensor device for quantifying luminescent targets. The device comprises a light source for exciting the targets, thus generating luminescence signals, and a detector for detecting these signals of the targets in a cell, resulting in a detected signal comprising a desired signal and a background signal. The detector has a spatial cell resolution and/or a time resolution that is so high that only a limited number of targets will be present in the cell when measuring at low concentration and/or that only a limited number of targets add to the cell in between two measurements. A change in the number of targets in the cell can be observed in the detected signal. The device comprises a processor configured to distinguish the desired and the background signal, and to combine the detected signals of the different cells and/or moments in time, to quantify the targets.

Abstract: A pulsed plasma analyzer includes a pulse modulator that controls an off-time of a pulsed plasma that includes a target radical, an optical spectrometer that measures optical emissions of the pulsed plasma after the off-time to determine optical emission data, and a concentration estimating module that estimates a concentration of the target radical during the off-time based on an initial optical emission value of the optical emission data that changes as a function of the off-time, and outputs an estimated concentration.

Abstract: A method of detecting a mineral or metal in soil causes at least a portion of a plant to burn to produce a light signature. The method also analyzes the light signature for the presence of the mineral or metal in the plant and determines if the light signature indicates the mineral or metal is present in the plant.

Abstract: In one embodiment, an imaging method may include receiving an intensity value of a first spectral channel associated with a pixel location. The intensity value of the first spectral channel may be based on electromagnetic radiation reflected from an object after being emitted from a narrow-band electromagnetic radiation source. The method may further include defining an intensity value of a second spectral channel based on the intensity value of the first spectral channel. The second spectral channel may be associated with a spectral region of electromagnetic radiation different from a spectral region of electromagnetic radiation associated with the first spectral channel. The method may also include associating the intensity value of the second spectral channel with the pixel location.

Abstract: This invention discloses a laser induced breakdown spectroscopy (LIBS) apparatus based on high repetition rate pulsed laser. The laser produces a train of laser pulses at a high repetition rate in the kHz (or even higher) range. When the laser beam hits the biological sample, it generates several thousands of micro-plasmas per second. Synchronized miniature CCD array optical spectrometer modules collect the LIBS signal from these micro-plasmas. By adjusting the integration time of the spectrometer to cover a plurality of periods of the laser pulse train, the spectrometer integrates the LIBS signal produced by this plurality of laser pulses. Hence the intensity of the obtained LIBS spectrum can be greatly improved to increase the signal-to-noise ratio (SNR) and lower the level of detection (LOD).

Abstract: A pulse train comprising chirped pulses can be used to excite a sample, such as for spectroscopic analysis. The respective chirped pulses can include a frequency sweep to establish a first frequency-domain comb. A width of frequency-domain comb peaks can be established at least in part by a total duration of the pulse train, and a bandwidth of the first frequency-domain comb can be determined at least in part by a bandwidth of the frequency sweep of the respective chirped pulses. A free-space or enclosed sample interaction region can be used.
